The Marcus Shelby Quartet is scheduled to perform at 8 p.m. Monday at UC Merced, inside the school’s Lakireddy Auditorium. According to the event’s Facebook page, Shelby will tell the remarkable story of Harriet Tubman, a runaway slave who worked in the Underground Railroad and became a leading abolitionist. Throughout her life, she worked to unite Americans of all colors and classes in a common struggle for liberty. The event is free to the public. UC Merced is at 5200 Lake Road.
